Fixing Bluetooth Connection Issues in Ubuntu 20.04 with TP-Link Adapter

Ubuntu 4

Bluetooth connectivity issues can be a frustrating experience, especially when you’re trying to get your work done or enjoy some music. In this article, we’ll guide you through the process of fixing Bluetooth connection issues in Ubuntu 20.04, specifically when using a TP-Link adapter.

Prerequisites

Before we begin, make sure you have the following:

  1. Ubuntu 20.04 installed on your system.
  2. A TP-Link Bluetooth adapter.
  3. Terminal access with sudo privileges.

Step 1: Install Bluetooth Management Tools

The first step in troubleshooting Bluetooth issues is to ensure you have the necessary tools installed. In this case, we’re going to install the “quick bluetooth connect” extension and Blueman.

Quick Bluetooth Connect is a GNOME extension that allows you to quickly connect and disconnect Bluetooth devices. You can install it from the GNOME Extensions website.

Blueman is a GTK+ Bluetooth Manager that provides a user-friendly interface for managing Bluetooth devices. You can install it by running the following command in your terminal:

sudo apt install blueman

The sudo command allows you to run commands with administrative privileges, while apt install is used to install packages.

Step 2: Check Bluetooth Adapter Status

Next, we need to check the status of your Bluetooth adapter. This can be done using the hciconfig command:

hciconfig

This command will display the status of your Bluetooth devices. Ideally, your device should be “UP” and “RUNNING”. If it’s “DOWN”, it may indicate a configuration issue.

Step 3: Update Bluetooth-Related Packages

Sometimes, outdated or incompatible packages can cause connectivity issues. It’s a good idea to update the bluez and libbluetooth3 packages, which are related to Bluetooth functionality. Run the following command to update these packages:

sudo apt update && sudo apt upgrade

The apt update command updates the list of available packages, while apt upgrade installs the latest versions of the packages you have installed.

Step 4: Remove and Re-pair the Device

If the issue persists, you can try removing and re-pairing the device. This can be done using the bluetoothctl command:

bluetoothctl

This command will open the Bluetooth control prompt. Here, you can use the remove, trust, and pair commands to remove, trust, and re-pair your device.

Step 5: Try a Different USB Bluetooth Adapter

It’s worth noting that TP-Link does not officially support Linux for some of their Bluetooth adapters, such as the UB400. If you’re using this adapter, consider trying a different USB Bluetooth adapter that is known to work well with Linux.

Step 6: Consult Online Resources

If none of the above steps resolve your issue, there are several online resources and forums where you can find solutions to Bluetooth issues on Ubuntu. Websites like Ask Ubuntu and Ubuntu Forums can be particularly helpful.

Conclusion

Bluetooth issues can be tricky to resolve, but with the right tools and steps, you can get your devices connected again. Remember to reboot your system after making changes to ensure they take effect. If you’re still experiencing issues, don’t hesitate to reach out to the Ubuntu community for help.

How do I open a terminal with sudo privileges?

To open a terminal with sudo privileges, you can press Ctrl+Alt+T to open the terminal. Then, you can run commands with sudo privileges by prefixing them with sudo. For example, sudo apt install blueman will install the Blueman package with administrative privileges. You will be prompted to enter your password before the command is executed.
